The FINANCIAL -- The Boeing Company reported first-quarter revenue of $23.4 billion reflecting higher commercial deliveries and mix, defense contract volume and services growth. GAAP earnings per share increased to $4.15 and core earnings per share (non-GAAP) increased to $3.64 reflecting strong performance across the company.
The company's cash flow guidance is increased to between $15.0 and $15.5 billion, driven by improved performance. Full year EPS guidance is increased by $0.50 to between $16.40 and $16.60, and core earnings per share (non-GAAP) guidance is increased to between $14.30 and $14.50 on performance.
"Across Boeing, our teams performed at a high level in the quarter, driving revenue and earnings growth at all three business units, increasing profitability and operating cash flow, and delivering more value to our customers," said Boeing Chairman, President and Chief Executive Officer Dennis Muilenburg. "Customers continue to recognize the value of our products and services, with strong orders booked in the quarter for defense, services and commercial offerings, including 221 net commercial aircraft orders."
"During the quarter we captured important new business, including an initial contract for 28 F/A-18 Super Hornets for Kuwait, a Ground-based Midcourse Defense program contract extension from the Missile Defense Agency, and we delivered the first Space Launch System intertank hardware to NASA. We achieved the first flight of the 737 MAX 7, and delivered the first 787-10 Dreamliner and the first 737 MAX 9. Within our services business, we received a follow-on contract to support the Royal Canadian Air Force's Chinook fleet, captured a landing gear exchange contract for Aeromexico, and released Self-Service Analytics to complement our digital solutions portfolio. All of these milestones demonstrated the value we bring to our customers through the strength of our One Boeing offerings."
"Our team's strong first-quarter performance, combined with the positive market outlook across our businesses and our confidence in executing on our production and development programs, gives us a solid foundation to raise our guidance for the year. Going forward, we remain focused on our disciplined growth strategy, improved profitability and cash flow to ensure we meet our commitments to our customers and our shareholders."
Operating cash flow in the quarter of $3.1 billion reflects planned higher commercial airplane production rates, improved performance, and favorable timing of receipts and expenditures. During the quarter, the company repurchased 8.9 million shares for $3.0 billion, leaving $15.0 billion remaining under the current repurchase authorization which is expected to be completed over approximately the next two years. The company also paid $1.0 billion in dividends in the quarter, reflecting a 20 percent increase in dividends per share compared to the same period of the prior year, according to the Boeing Company.
Total company backlog at quarter-end was $486 billion and included net orders for the quarter of $34 billion. Backlog was up from $475 billion at the beginning of the quarter, which has been adjusted to reflect the adoption of the new revenue recognition standard (ASC 606).
Commercial Airplanes first-quarter revenue was $13.7 billion reflecting higher deliveries and mix. First-quarter operating margin increased to 11.0 percent, reflecting strong operating performance on production programs.
During the quarter, Commercial Airplanes delivered 184 airplanes, including delivery of the first 787-10 Dreamliner to Singapore Airlines and delivery of the first 737 MAX 9 to Lion Air Group. The 737 program reached additional milestones during the quarter, including first flight of the 737 MAX 7 and firm configuration of the 737 MAX 10. The 737 program has captured over 4,400 orders since launch for the 737 MAX, including a recent order from Jet Airways for 75 additional airplanes. Reflecting the strength of the cargo market, we now plan to increase the production rate on the 767 program from 2.5 to 3 per month beginning in 2020. Development on the 777X program remains on track as production began on the first 777X fuselage for structural testing.
Commercial Airplanes booked 221 net orders during the quarter. Backlog remains robust with over 5,800 airplanes valued at $415 billion.
Defense, Space & Security first-quarter revenue increased to $5.8 billion driven by C-17, international fighters, and weapons volume. First-quarter operating margin increased to 11.3 percent on solid execution and mix.
During the quarter, Defense, Space & Security was awarded an initial contract for 28 F/A-18 Super Hornets for Kuwait, a contract for the final C-17 for India, and an extension for Ground-based Midcourse Defense development and sustainment from the Missile Defense Agency. We continue to progress on development programs as the KC-46 Tanker program completed fuel on-load certification testing, the first Space Launch System intertank hardware was delivered to NASA, and the second Commercial Crew spacecraft successfully achieved power-on.
Backlog at Defense, Space & Security was $50 billion, of which 36 percent represents orders from international customers.

At quarter-end, Boeing Capital's net portfolio balance was $2.9 billion. Total pension expense for the first quarter was $40 million, down from $97 million in the same period of the prior year. Revenue in other unallocated items and eliminations decreased primarily due to the sale of aircraft previously leased to customers in the first quarter of 2017. The effective tax rate for the first quarter decreased from the same period in the prior year primarily due to the reduction of the federal tax rate to 21%.
